No settings might be better. If I take my laptop from one site to
another, keeping my previous resolv.conf intact, and NM doesn't remove
it, then my laptop will try to query the previous site's DNS. They may
not like that; depending on how paranoid they are, they may even take
measures to block my traffic. Even if not, I may see some really
bizarre DNS behavior which could be difficult to troubleshoot, whereas
having no DNS at all will be very obvious very quickly.
I don't use NetworkManager, so I don't know the answer to this question:
is there a way to tell it not to clobber portions of your network
configuration, and/or to provide it with defaults if it can't determine
values for a particular option? That seems like the most logical way to
handle this scenario.
